SPECIFICATION forming part of Letters Patent No. 308,012, dated November 11, 1884.

Application filed March 13, 1884. (No model.)

To @ZZ whom ,it may concern.-

Be it known that I, ALEXANDER W. THOMP- sON, a subject of the Queen of GreatBritain, residing at Hagersville, in the county of Haldimand, Province of Ontario, Dominion of Ganada, have invented certain new and useiul linprovenients in Machines for Cri inpiii g the Uppers of Boots and Shoes, of which .the following is a full, clear, and exact description.

My invention relates to an improvement in machines for crimping the uppers of boots and shoes.

The machine is composed, essentially, of a slotted bed or former and a reciprocating plun- I 5 ger operated by a lever and any suitable power, the leather being forced by the descent of the plunger through the slot in the bed, receiving in the operation its shape from the former.

The invention consists in various peculiari- 2o ties oi' construction tending to increase the efficiencv of the machine, and it is illustrated in the accompanying drawings, in which- Figure l is a side elevation of the machine. Figf2 is an end elevation. Fig. 3 is a plan. Fig. 4 shows both a side elevation and a plan of the slotted keeper-plate, and Fig. 5 is asectional view of the plunger.

B B indicate the frame-work of the machine, made preferably of metal and supported by 3o standards I. The inner side of each traine is recessed for a portion of its length, so that a. slot is formed when the side pieces are bolted together, as shown in Fig.` 3. On the bolts (four of which are preferably used) and be- 3 5 tween the face of the side pieces and the nuts E are rubber washers or cushions, which yield sufficiently to permit a slight lateral movement of the side pieces B when the plunger enters the slot. 4o D represents the former, made preferably of metal and of the shape which the leather is to assume. The former is secured within a recess in the upper edges of the frame B, and upon it rests a slotted metallic keeper-plate, C, Fig. 4, which ts the former accurately. The leather is held between the plate G and the former. The dotted lines MI show the ex- `H H, pivoted at both ends, respectively, to

the plunger and bracket. The vmovement of these rods tends to carry the plunger forward 6o as it is depressed, causing it to enter the former in a precisely vertical plane. A leaf-spring, L. is attached to the former to secure the edge of the leather.

ln operating niy machine, the leather is secured between the plate C and the former D. The plunger A is then forced throii gh the slot, carrying the leather with it' and forming the crimp.

Obviously the machine may be operated by '7o.k

hand, or the lever connected in any way to power.v

That I claim is-f l. The combination of the longitudinal side pieces recessed on their inner faces intermediate of their ends to form a slot when brought together and constituting a bed-frame, the former secured within a recess in the bedframe, the slotted keeper fitted to the former, and the hinged plunger, substantially as described.

2. The bed-frame composed of yielding side pieces, B, in combination with the former D, plate C, plunger A, and parallel rods H H, substantially as described.

3. The combination, with the frame, of the operating-lever G, the suspended plunger, and the pivoted parallel rods H H, substantially as described.
